Unlike prokaryotes, eukaryotic cells also possess internal membranes that encase their organelles and control the exchange of essential cell components. Both types of membranes have a specialized ...

Microporous membranes are thin polymeric film, or filament, walled structures made up of millions of microscopic pores. Typically, they have an open morphology pore size ranging from 0.03 μm up to 10 ...

Ion exchange chromatography involves either anion exchangers or cation exchangers, depending on the membrane’s specialized chemistry. Anion exchangers are used with negatively-charged biomolecules ...

At least 10 different types of globular protein domain are known that bind membrane phospholipids. Acidic phospholipids (especially phosphatidylserine and phosphoinositides) are the primary ...

Lipids, or fats, are essential to life. They form the membranes around cells, protecting them from the outside. In nature, ...

The Visking tubing is the selectively permeable membrane. Water moves by osmosis from the high water concentration (dilute solution) in the beaker into the low water concentration (concentrated ...

How did the first living cells come to exist? How did these early protocells develop the structural membranes necessary for cells to thrive and assemble into complex organisms? New research has ...
